WG Meeting Week of February 19th on trace_event

[mikeal]

We should have a working group meeting this week, there's a lot to discuss but because we have so many people I think that we're going to have to limit the meeting in scope and ask that people unfamiliar with the topic watch the feed rather than get on the hangout since space on hangouts-on-air is limited.

I think we should discuss v8/chrome's trace_event and how this can be leveraged by iojs. In particular, I've heard people wondering if we might actually be able to replace AsyncWrap with trace events which would make it easier to write more unified tooling. If changes to the debugging plan this big are being considered we should shake them out now :)

Off the top of my head I think we need @natduca @ofrobots @trevnorris and @thlorenz and probably others.

[arunoda]

I'm happy to watch the feed :)

[rmg]

I don't think I have anything to offer on this one, and I can always feed my input through @sam-github or @piscisaureus if I hear something on the youtube stream.

[GlenTiki]

I'll watch the feed. :)

[bnoordhuis]

I'll try to join but I'm moving next week and I may not have a working internet connection on the 19th yet.

[natduca]

Happy to join.

[thlorenz]

We should get Ali from Google (don't remember his last name or github handle) into the discussion as well as he has expressed interest in helping us adopt the v8 tracing format.
Some of you (i.e. @mikeal) may have talked to him at NodeSummit and remember his handle to summon him in here.

I myself would be available any day of the week and early Friday for a meeting.

[thlorenz]

Also linking in @natduca's very detailed notes regarding tracing in chromium since I believe that some points in there should become part of the discussion.

[ofrobots]

I'll be happy to join. (Hi Thorsten!)

Awesome @ofrobots, glad to have you :)

[piscisaureus]

That sounds a bit strange to me since AsyncWrap and tracing aren't really related. Potentially you're thinking about replacing @trevnorris' tracing support?

[mikeal]

@piscisaureus I think @piscisaureus and @ofrobots can probably explain it better.

[sam-github]

I'd like to be involved, I'm working on these areas for StrongLoop ATM.

[sam-github]

Also, is there a target day? Later in the week would work better for me, morning would probably help cross time zones from North American pacific coast through Europe.

[kraman]

Hi, I would like to join this WG as well. I am working with Sam on the same areas within StrongLoop. Thanks

Doodle for finding the best time on Thursday. http://doodle.com/yds5u6ns86t85tuu

You can't just replace AsyncWrap. It's part of how the asynchronous class structure is created. All that you could do is remove the user exposed hooks. Though the advantage to AsyncWrap is that it is VM independent.

[mikeal]

replace was probably the wrong way to put it, it was more like "feed asyncwrap events in to trace_event"

[Qard]

I put myself up for any time, though I might just lurk in IRC if it gets too full.

I'm not sure how much I have to contribute to the conversation anyway. I've only just recently started digging into tracing the native side.

Doodle is closed, Thu 2/19/15 2:00 PM – 3:00 PM PST.
